Might be best for the Jazz to pass on point guards this year and just go with Devin. Next year Marshall will be coming out and he is a pure PG in the mold of Jason Kidd and Deron Williams. The Jazz will have around 8-12 which should be plenty high enough to get him.
I do like Marshall a lot. Hopefully he will be available in the late part of the lottery/ early non-lottery, which is where I think we will be next year. He is definitely seems to be one of the more "pure" PG's in college (didnt he set the assist record at UNC this year for something?) and he would be perfect if we manage to actually acquire scoring wings and our big men develop strongly.
